Criselda Sigler

Criselda Sigler serves as a key procurement professional within the Naval Supply Systems Command Fleet Logistics Center Norfolk, supporting the Department of the Navy’s mission to sustain operational readiness through specialized logistics and engineering services. She manages acquisitions aligned with critical fleet sustainment needs, focusing primarily on the design, installation, and maintenance of commercial and industrial refrigeration and climate control systems essential to naval platform integrity. Her work ensures mission-critical environments—from shipboard compartments to shore-based maintenance facilities—maintain optimal thermal conditions for equipment and personnel, directly contributing to maritime superiority through reliable infrastructure. Sigler maintains consistent working relationships with a select group of high-performance contractors, including Obsidian Global, LLC, Deloitte & Touche LLP, Advania Island Ehf., Complete Parachute Solutions, Inc., and Computational Physics Inc. These partnerships reflect a preference for technically proficient vendors capable of delivering complex, mission-specific environmental control solutions, often involving integrated systems engineering and compliance with naval technical specifications. Her contracting approach emphasizes performance-based outcomes, technical validation, and long-term service support over commodity procurement. Her procurement portfolio shows no use of socioeconomic set-asides, with 100% of acquisitions competed fully and open to all eligible vendors. This reflects a strategic emphasis on technical capability and mission necessity over socioeconomic preferences, prioritizing the most qualified providers regardless of business size or certification status. The agency’s sole NAICS focus—333415 for air-conditioning and commercial/industrial refrigeration equipment manufacturing—reveals a deep specialization in thermal systems for defense applications. Sigler’s expertise centers on procuring precision-engineered climate control hardware, including chillers, condensers, and integrated HVAC systems designed for harsh maritime environments, ensuring compliance with MIL-SPEC standards and lifecycle durability requirements.
